Breathing sound measurement device and sleeping state measurement system

Abstract

A breathing sound measurement device includes a measurement section configured to be brought into contact with a skin of a front neck of a subject and measure breathing sound of the subject and a wearing section configured to have a first end connected to the measurement section and have elasticity to extend in a circular arc shape along an outer circumference of the subject's neck. The wearing section has a second end provided with a pressing portion configured to be pressed against a skin of a rear neck opposite a right front neck with respect to a midpoint between right and left halves of the subject's neck.

The invention claimed is: 
     
         1 . A sleeping state measurement system comprising:
 a breathing sound measurement device; and   a terminal device comprising one or more of a smartphone and a tablet computer,   the breathing sound measurement device comprising:   a measurement section configured to acquire breathing sound of a subject with a contact section brought into contact with a skin of a front neck of the subject, wherein the measurement section includes a first substrate to which a microphone is attached;   a wearing section extending in a circular arc shape along an outer circumference of a subject's neck to a rear neck opposite the front neck of the subject;   a hinge section that couples a base end of the measurement section and a base end of the wearing section to each other; and   a vibrator configured to impart vibration to the subject's neck,   wherein the hinge section includes: a rotating shaft portion configured to circumferentially rotatably support the measurement section and the wearing section; and a biasing portion configured to bias the measurement section and the wearing section in a closing direction so that the subject's neck is held from outside when the breathing sound measurement device is worn on the subject's neck,   the terminal device includes: a communication module configured to communicate with the breathing sound measurement device; and a display screen,   the terminal device receives a measurement result from the breathing sound measurement device and displays information on the subject's snoring period, normal breathing period, and apneic period in at least either graph or numerical form on the display screen on the basis of the measurement result thus received, and   the terminal device displays, on the display screen, a juxtaposition of first sleep information including information on the subject's snoring period, normal breathing period, and apneic period in a vibration mode in which the vibrator is caused to vibrate and second sleep information including information on the subject's snoring period, normal breathing period, and apneic period in a non-vibration mode in which the vibrator is prohibited from vibrating.   
     
     
         2 . The sleeping state measurement system according to  claim 1 , wherein,
 in the vibration mode, the vibrator is configured to vibrate during at least either the subject's snoring period or apneic period and is configured to not vibrate for a predetermined period of time in response to the sleeping state measurement system beginning to measure a sleeping state of the subject.   
     
     
         3 . A sleeping state measurement system comprising:
 a breathing sound measurement device; and   a terminal device comprising one or more of a smartphone and a tablet computer,   the breathing sound measurement device comprising:   a measurement section configured to acquire breathing sound of a subject with a contact section brought into contact with a skin of a front neck of the subject, wherein the measurement section includes a first substrate to which a microphone is attached;   a wearing section extending in a circular arc shape along an outer circumference of a subject's neck to a rear neck opposite the front neck of the subject;   a hinge section that couples a base end of the measurement section and a base end of the wearing section to each other; and   a vibrator configured to impart vibration to the subject's neck,   wherein the terminal device includes: a communication module configured to communicate with the breathing sound measurement device; and a display screen,   the terminal device receives a measurement result from the breathing sound measurement device and displays information on the subject's snoring period, normal breathing period, and apneic period in at least either graph or numerical form on the display screen on the basis of the measurement result thus received, and   the terminal device displays, on the display screen, a juxtaposition of first sleep information including information on the subject's snoring period, normal breathing period, and apneic period in a vibration mode in which the vibrator is caused to vibrate and second sleep information including information on the subject's snoring period, normal breathing period, and apneic period in a non-vibration mode in which the vibrator is prohibited from vibrating.   
     
     
         4 . The sleeping state measurement system according to  claim 3 , wherein,
 in the vibration mode, the vibrator is configured to vibrate during at least either the subject's snoring period or apneic period and is configured to not vibrate for a predetermined period of time in response to the sleeping state measurement system beginning to measure a sleeping state of the subject.
